Scoring Saw Blade Orthogonal Adjustment via Eccentric Gear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel dividing systems face challenges in precisely aligning and adjusting the scoring saw blade for thick stacks of workpieces, particularly with surface coatings, which can lead to tearing during the cutting process.
Innovation Solution
A panel dividing system with a self-locking, compact eccentric gear mechanism that allows precise orthogonal adjustment of the scoring saw blade, combined with a vertical input shaft and absolute measuring system, enabling accurate positioning and vertical scoring capabilities within a narrow machine foot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an electrically operable threaded rod is used to adjust the scoring saw blade, then the adjustment can be performed, but the device becomes complex and large in dimensions
Solution Approach 1:
The patent extracts the adjustment function from a complex electrically operable threaded rod system and implements it through a simple manual adjustment mechanism with a adjusting screw that directly modifies the position of the scoring saw blade holder, eliminating unnecessary complexity while maintaining adjustment capability
Solution Approach 2:
Instead of using a complex expansion mechanism to achieve adjustment, the patent inverts the approach by using a compression-based adjusting screw mechanism that pushes the scoring saw blade holder to achieve precise positioning, simplifying the overall structure
2Length of moving object
If the scoring saw is made narrow to fit in machine foot, then space is saved, but adjustment capability and stability are reduced
Solution Approach 1:
The patent relocates the adjustment mechanism from a lateral configuration to a vertical configuration, with the adjusting screw acting vertically on the scoring saw blade holder from above, allowing the scoring saw to maintain a narrow lateral profile while preserving full adjustment capability through vertical movement
Solution Approach 2:
The adjusting screw mechanism is nested within the compact structure of the scoring saw assembly, with the screw shaft and adjustment components integrated into the vertical space above the scoring saw blade holder, maintaining a narrow overall width while incorporating full adjustment functionality
3Manufacturing precision
If the scoring saw blade is adjusted laterally, then alignment can be achieved, but the device width increases
Solution Approach 1:
The patent changes the adjustment dimension from lateral (horizontal) to vertical, with the adjusting screw moving the scoring saw blade holder up and down to achieve alignment, thereby maintaining a narrow device width while still achieving precise blade positioning through vertical displacement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures precise alignment and adjustment of the scoring saw blade, preventing surface tearing and allowing for efficient cutting of thick workpieces, even with surface coatings, by enabling vertical scoring and maintaining a narrow profile for easy integration into existing machinery.
Implementation Method 1
a) an eccentric gear (78, 82), whose input shaft (74) is essentially vertical, whose adjustment screw (88) acts on the eccentric disk (82) indirectly

AI summary
The panel saw comprises a carriage (60) provided along a sawing line. A scoring saw and a main saw are positioned on the carriage. The scoring saw is formed with a bearing portion (68) mounted with a scoring saw blade (30). The bearing portion is moved in a direction (32) orthogonal to the plane of scoring saw blade relative to the bearing portion (70) by an adjusting device. An input shaft is mounted on a bearing portion (70). The end of eccentric disc is coupled with the bearing portion (68). An independent claim is included for method for operating panel saw.
